The Green Line Infrastructure Alliance, a partnership between NationalGrid and Anbaric, proposes to build the 60-mile, underground and underwater electric transmission cable to deliver 400 MW of clean energy to New England, enough to power 240,000 homes during peak demand,according to Anbaric. The preferred cable route will interconnect with thee xisting 230-kV AC power grid at a new converter station in Beekmantown,N.Y., travel under Lake Champlain, and connect to the 345-kV AC system with another new converter station in New Haven, Vt. All land cables will be underground, Anbaric added, noting that the cable will operate at+/-150-kV – DC. The project is expandable to 800 MW as the need arises in the future. Anbaric also said that permitting for the project will begin in 2016, with construction scheduled to begin in 2017, and the project could be in service by 2019/2020.
